in thefillers "and" are of considerabledepth in order to provide a plane surface for the" wedges 11 to bear against. This peculiar formation also adds stiflness to the. filler members. The edge portions 1313 of the filler members are depressed below the: central portion and the edges of the sectionsi 7 abutinents on the intermediate ears slightly fromthe horizontal. V

, From inspection of Fig. 7, the mannerin which the sections and fillers lock will be readily seen. As thereshowmthe lugs on thesections project through. the. apertured ears on the filler membersand. the wedges 11 arefdriven in place in the recesses in. the "lugs. I The wedges bear against the abut- -ments [17, the upper and lower wedges drawing, the sections and filler members together onv a horizontal line, and the intermediate wedges" drawing. them together on a vertical lines" It will be seen that by this arrangement 7 the sections will be joined together with great rigidity and that. any sagging of the.

overhanging portions will be prevented by the mtermecliate'wedges, and all. inner surfaces kept flush with one another. The size of the form can be readily varied by em:-

p-loying filler members of greater or less width than the ones shown without. necessitating any change'in the other parts. "It will be apparent that the sections: can be readily assembledand taken apart and that when assembled! and locked, are: united. into a rigid structure.

Having thus described my invention and illustrated its use, what I claim as new and desire to secure byLetters'Patent is the. 01 lowingr'z" 1; A column form comprising-in combination a plurality of sections formed in such manner that the area of the form isgreater at-the top than at the bottom when the sectionsare assembled, said sections being provided with'a lug adjacent to each end having asubstantially vertically disposed aperture and being provided with an intermediate lug having-av substantially'horizontally disposed aperture, filler members having apertures to receive. the. said lugs, and having avertically disposed abutment adjacent to each end aperture and a horizontally disposed abutment adjacent to each intermediate aperture,- and -Wedges for the lugs engaging saidabutments and adapted to draw the 'vertical edgesof the sections and filler-together and to drawthefaces. of the sections and filler membersflush intermediate the ends thereof.

2.. Acolumnform comprising a plurality ofsec'tionssomeof which areproyidedwith openings, apertured lugs on the other sections adapted to fit into said openings, abutments formed adjacent to said openings some of wh ch; are disposed substantially vertically and others substantially horizontally, and wedges for thelugs engaging said abutments whereby the vertical edges of the: sections. are drawn togetherand the faces of the sections drawn flushfwheni the Wedges are driven in place.

In testimony whereof I have hereunto signed my name in theppresence of the two subscribed witnesses. 1
